Around a third of a person’s life is spent asleep. Previous studies have reported an association between sleep disordered breathing, like OSA, and pregnancy complications such as pre-eclampsia, gestational diabetes, and preterm birth. We recently discussed a stillbirth bundle from Australia which includes patient education on sleeping practices and stillbirth risk. Does maternal sleeping position ready influence stillbirth risk? Some data says NO, but there’s a catch to those. Other population level data says YES. Why the difference? And why is the position the mother STARTS to sleep very important here? Listen in for details as we walk down the timeline of data from 2011 to present day.
